She's going to add it as an amendment to another bill. They know it'll never pass on its own.

^ This.

When they couldn't pass a mandatory seatbelt law at the federal level, they simply linked federal highway funding to each state enacting their own seatbelt law.

It ain't over.

My suspicion is that they Feinstein bill was a false flag, intended to make a later bill focused on magazine capacity, ammo limits, etc... look "more reasonable" by comparison. That way, the liberal whiners and their partners in the media can crow about how "accommodating" their new bill is...

The Senate still plans to vote on the ban, but only as an amendment to the larger gun bill. Feinstein also asked for a second vote on a measure that would just ban high capacity magazines for assault weapons; that's likely to garner more support.
